Description

technical field

[0001] The invention relates to a catalytic wet oxidation method, in particular to a catalytic wet co-oxidation method for degrading nitrobenzene pollutants. Background technique

[0002] With the rapid development of industrial technology and the continuous expansion of production scale, various industrial wastewater containing high concentrations of organic pollutants that are difficult to biodegrade are increasing. It is difficult to meet the technical and economic requirements of purification treatment by conventional biochemical methods. As an important industrial raw material, nitrobenzene compounds are mainly used in dyestuffs, medicines, pesticides, explosives and other industries. The production wastewater of these industries contains a large amount of organic pollutants such as nitrobenzene, aniline, and nitrotoluene; these organic pollutants are biologically refractory substances and cannot be directly treated by biochemical methods. In addition, ...
